yApplication filed March 1, 1915. Serial No. 11,374.

To all 'whom z'z may concern: l

Beit known that I, GEORGE H. DILLON, a citizen of theUnited States, 'residing at Sawtelle, in the county of Los Angeles andy State of California, have invented a new and useful Anchoring Device, of which the following is a specication.

This invention is speciallyv adapted for anchoring railway rails to Wooden ties but is applicable to other uses where a spike or the like is employedV for detachably fastening parts together. v

An object ofthe invention is to provide means whereby a railway rail or other body may be detachably fastenedv to a railway tie or other support in such a manner as to avoid any accidental release of the anchoring device by vibrations or by shrinkage of the wood or other material into which the spike is driven.

An object ofthe invention is to use as a part of the anchoringV device a common railway spike ofV the kind now in use and to absolutely secure said spike against accidental loosening or withdrawal and Lyet to make provision whereby the spike can be released and withdrawn and can again be inserted, driven Vhome and secured `as rmly as before.

The invention includes an anchor attachment to be used in connection with the commonV railway spike or the like andalso includes 'said anchor attachment and a speciiic releasablelock for connectingfsaid anchor attachment with the spike.

An object of the invention is to providey means which reinforce the spike to secure a railway rail to a railway tie. i

Other objectsy are cheapness, simplicity of construction, ease of application, ease ofre-l lease, and avoidance of destructivey action upon the bodylto which the anchoring deviceis applied` The accompanying drawings illustrate the invention. o

\ Figure l is a fragmental perspective view of the reinforced anchor device in anchoring` position to secureza railwayrail yto a railway tie. Fragments of the. rail, railplate and tie arel alsovshown, theflowerportion of said tiebeingbroken awayto eX- pose the embedded portion of the anchor;y

"Fig is aside .elevation of parts shown in Fig; 1 afterthe spike has beenk driven and withdrawn and" the anchor 'attachment placed in position in the hole thus formed and a spike in position ready to be driven home preparatory to being fastened as in Fig. 1.

Fig. 3 is a sectional view analogous to Fig. 2 showing the spike driven home and secured.

Fig. '4 is an elevation .of the anchor attachment detached and viewed from the left of Fig. 3, the locking means being shown extended above the anchor attachment for clearness of illustration.

kFig. 5 is a fragmental view illustrating a modified form in which the device may be embodied. f'

The'anchor attachment consists of limb 1 having at one end a sharp bend forming a detent 2 and at the other end a knuckle 3 through which extends a pivot l pivotally securing an anchor link 5 to said anchor at. tachment. Said link may be of any suitable construction, either solid metal or in the for-m of a U-shaped strap that may or may notbeprovided. with a cover portion 5.

`said link being perforated to receive the pivotf'f and also perforated a distance from said pivot to receive a pin v6, which pivots a latch 7 to the link 5. Said latch may conveniently be made of two links such as are used in the construction of an ordinary sprocket chain, said links beingpivoted to opposite sides of the anchor link and provided `at their free ends with perforations 8 through which a key 9 may be inserted.

The knuckle 3 overhangs upon the detent side of the limb 1 to thus form a channel b in which the key 9 is adapted to seat to latch the links 5 and 7 down in place.

The; spike is of the usual construction having a bevel point 10 and straight body 11, Aand ahead extension 12 to extend over the liange v123 of the railway rail.A

, Inorder to apply the anchor, the spike or the like is first driveninto Vthe Atie 15 -to make a suitable yhole 16 and is then with-k drawn. Then the anchorattachment limb 1 is inserted into thehole to a depth which willbring` the knuckle 3 just above the level of thespike yhead when it is driven homeonto the flange of the rail. This is gaged byfmaking the detent ofthe same width as the spikevbody and the anchor of a length equal to thecombined length vof the/'spike andY head above the bevel point y10 of the spike, soy that after the spike 'has been driven to the depth to which it is designed to be seated in order to hold the rail flange and then withdrawnr and the anchor attachment limb 1 inserted, said limb will? automatically adjust itself to the right depth by coming to rest on the converging walls of the hole. y

Positive gage means tolimit the depth to which the anchor may drop in the hole 1G may be provided in the form of a suitable shoulder lion the limb 1, .near the top' home alongside of said limb with the head extension on the top of the flange the detent 2 is projected laterally into the tie near thek bottom ci the hole, see Fig. 3, after which the anchor link 5 is swung over onto the Vhead of the spike and the latch swung down into position below the overhanging knuckle 3*, and the key 9 is then inserted through the holes S in the Vends of the latch and underneath the overhanging knuckle thereby locking the anchor to the spike.

Said key may be of any suitable construe` tion and maybe an ordinary' wire nail driven through and bent to prevent accidental withdrawal.

in the modification shown in Fig. 5, the key 9' is assembled in place between thel latch links .7 and is provided with a bent handle portion 17 by which to turn said key and a locking lip' 18 while the latch links i are made sufficiently long to swing over the overhanging knuckle 3 when said lip is turned outwardly, as indicated by dot and dash lines Fig. 5. After 'swinging the latch down into position the key may be turned to throw the lip under they overhanging knuckle and thereby lock the anchor and spike together.

lt is understoodthat the hole to receive the'detent may be made by any other suitable rneans instead of the spike. y

'When it is desired tordetach the anchor device the bent keyV of Figs. 1 to fl will be straightened and driven' out, the latch raised and the spike thus released is then pulled in the usual way. llhe anchor piece or limb 1 may then be detached by inserting .the spike to wedge it rom'the side of the spike' hole, thus withdrawing the detent from suoli wall.

Since the detent is formed as a sharp lateral bend formed at the Ylower end or" the neeafiea anchor, the insertion ofV the spike to wedge loose the anchor is easily eiiected and likewise the driving oi'- thev detent into tlie'tieis edected inl a: practicall way when the spike is drivendown from the position shown in Fig; 2;

Y In the form shown in Fig. 5 the key will be' rotated to release it and will then `r be withdrawn thus releasing the spike as before.
